MAINTENANCE
5-3 ROUTER BITS:
Router bits will need to be sharp to provide a clean, well formed mortise. Check router bits once daily
and replace if the router bit looks burnt or dull.
5-4 DRILLS:
Drill bits need to be kept sharp at all times Failure to do so will result in the use of additional electrical
current and shorten motor and bearing life. Here again, we believe we can do a superior job in sharpen
-
ing your drill bits and we solicit this work from you.
5-5 FILTERS:
The air filters on your machine are designed to further clean air that is not heavily laden with moisture
or impurities. If excessive water or pipe scale, etc., is present in the air to the filters, the filters will clog up
and pass through the excess water, etc. For this reason if you do not have an in-plant air cleaning system,
we suggest you contact the Norfield Service Department or your local air system supplier for assistance
in correcting this problem. Water present in air cylinders and valves will severely shorten their life by up
to 90%! Check the air filters daily see figure 3.1. The drain on the pre-filter (particulate) is automatic, but
still needs to be checked daily to make sure it is “dumping” all the water. The particulate air filter will
require cleaning at intervals dependent on the quantity of impurities in your air supply. The secondary
filter (coalescing) is designed to remove very small impurities and oils from the air. This filter must be
replaced when the element appears discolored or dirty. NOTE: A DISCOLORED COALESCING FILTER
INDICATES A POSSIBLE PROBLEM WITH THE UPSTREAM AIR SUPPLY
5-6 REGULATOR:
Set regulator at 90 PSI
5-7 AIR TOOL LUBRICATOR:
Set lubricator to drop (2-4) drop per minute, with one air tool running. This is not a critical adjustment,
but excess oil in the air serves no useful purpose. Use 10 wt. turbine oil to refill the lubricator.
5-8 CYLINDERS:
Keep cylinder shafts clean to prevent excess wear. As seals in all cylinders will take a “set” when not
operating, cylinder manufacturers strongly recommend that all cylinders be cycled at least two times
each morning before placing a door and jamb in the machine. This will allow the cylinder seals to regain
natural sealing ability and will lengthen cylinder life considerably.
DO NOT USE HYDRAULIC FLUID, OIL CONTAINING ADDITIVES
OR ANY SUBSTANCE NOT RECOMMENDED BY NORFIELD AS
THIS MAY CAUSE DAMAGE TO THE MACHINE AND POSSIBLY
VOID YOUR WARRANTY.
